  • Publication number: 20150076032
    Abstract: Heavy gas oil components, coking process recycle, and heavier hydrocarbons in the delayed coking process are cracked in the coking vessel by injecting a catalytic additive into the vapors above the gas/liquid-solid interface in the coke drum during the coking cycle. The additive comprises cracking catalyst(s) and quenching agent(s), alone or in combination with seeding agent(s), excess reactant(s), carrier fluid(s), or any combination thereof to modify reaction kinetics to preferentially crack these components. The quenching effect of the additive can be effectively used to condense the highest boiling point compounds of the traditional recycle onto the catalyst(s), thereby focusing the catalyst exposure to these target reactants. Exemplary embodiments of the present invention can also provide methods to (1) reduce coke production, (2) reduce fuel gas production, and (3) increase liquids production.

    Abstract: Petroleum cokes derived from extra-heavy crude sources can be made more amenable to quenching by adding water or a water/light oil mixture to the coker feed downstream of the furnace. The coke product resulting from this addition of normally volatile liquids to the hot coker feed is still relatively dense but is more friable and usually is in a compact, relatively free-flowing, granular form. The coke is more amenable to uniform quenching in the drum and so can be cut and discharged with a reduced risk of eruptions and a reduced risk of fires in the coke pit or when the coke is subsequently handled and transported.

    Abstract: A system for producing petroleum products from oil shale includes one or plural kiln lines made up of plural series-connected, indirect-fired, inclined rotary kilns. Plural kiln lines are operated for parallel processing. Oil shale is advanced through kilns in succession and exhausted from each kiln line substantially free of hydrocarbons. Successive kilns along the advancement of oil shale are maintained at successively higher temperatures. A fuel distinct from hydrocarbons in oil shale, such as syngas from a gasifier or hydrogen gas from a separator, drives pyrolysis to extract hydrocarbons. A refining unit located proximate to the kiln lines upgrades extracted hydrocarbons into petroleum products and separates the petroleum products by criteria. A heat extraction unit recovers heat from exhausted oil shale for reuse in kilns. A method involves drying oil shale followed by heating dry oil shale in successively hotter pyrolysis environments.

  • Patent number: 7611609
    Abstract: A method for producing non-recovery/heat recovery coke may include the steps of providing a container, disposing a volume of loose coal into the container such that a vertical dimension of the volume of loose coal in the container is smaller than a horizontal dimension of the volume of loose coal, applying a force to the coal in the container to produce a volume of compacted coal having a substantially uniform density which is larger than that of the loose coal, disposing the compacted coal into a non-recovery/heat recovery type oven, and heating the compacted coal to produce coke. The method may also include the steps of providing a container, and moving the non-recovery/heat recovery coke mass from the oven at a substantially constant elevation to the container, quenching the coke mass in the container to produce a quenched coke mass, and removing the quenched coke mass from the container.

  • Publication number: 20090229965
    Abstract: A system and a method of decomposing organic waste are provided. The system decomposes organic waste in a decomposition chamber without use of enzymes, additives, or microorganisms. In one embodiment, the system decomposes organic waste within 24 hours and deodorizes the odor of decomposing organic waste during decomposition process. The system provides sufficient heat and operating conditions to evaporate moisture from the organic waste without burning the organic waste. The byproduct of the organic waste after decomposition process by the system is substantially homogeneous material that is reduced in volume compared to the organic waste. In one embodiment, the system reuses or recycles water and heat used in the system for different processes in the system. The system includes a blower that provides flow of the moisture inside the system.

  • Patent number: 7048831
    Abstract: The present application discloses a method and apparatus for purging oxygen from a sealed container interior and a purge substance used in such method. The method is exemplified herein in an improved batch process and apparatus for the thermal decomposition of hydrocarbon containing material in a sealed reactor interior. According to the present invention the improved batch process may comprise, 1) loading the hydrocarbon containing material into and sealing the reactor, 2) purging or expelling oxygen from said reactor, and 3) heating said reactor to a predetermined temperature so as to obtain decomposition products, the improvement residing in the purging step including loading the reactor with an oxyphilic solution prior to sealing and heating the interior of the sealed reactor to a predetermined temperature to induce the oxyphilic solution to drive oxygen out of the interior of the container through said gas evacuation component.

    Abstract: A process for treating industrial and/or urban waste includes the steps of drying the waste; effecting thermolysis of the dried waste by direct contact with warm gases, and washing solids resulting from the thermolysis with water to effect dechlorination thereof. Thermolysis is effected by direct contact of the waste with warm gases having a low oxygen content and water for washing the solids is obtained from condensation of vapors generated during drying of the waste A plant for treating industrial and/or urban waste includes a drier for drying the waste, a reactor for thermolyzing the waste, washing the solids from the reactor with water, such as from a condenser, to dechlorinate the solids, and a gas generator to generate warm gases, of which a part of the warm gases are used to heat the drier.

  • Patent number: 5478442
    Abstract: A rotary hearth calciner for treating petroleum cokes with a puffing inhibitor has a horizontal or inwardly sloping hearth floor rotatable around a vertical axis for receiving particles of coke to be calcined and a central opening in the hearth floor for discharging the coke into a soaking pit. A water cooled, refractory covered feed pipe extending downward into the calciner interior has an inlet for connection to a source of petroleum coke puffing inhibitor and an outlet near the edge of the hearth central floor opening for adding the puffing inhibitor to the coke as the coke is discharged from said hearth floor. The feed pipe outlet is approximately at or below the level of the hearth floor to reduce loss of inhibitor in gas flow above the hearth floor. A puffing inhibitor such as sodium carbonate is supplied by a screw feed mechanism to the feed pipe to add the puffing inhibitor at a desired rate for reaction with the coke. The coke is normally maintained in the soaking pit for about 30 minutes at 1200.
